I would like to have had the Underwood Xtreme Defender 38spl included in this test.
From what I've seen on You Tube, it looks impressive.

1961-1965
"This was followed by firing three rounds into a block that had been covered with a layer of denim, a layer of insulation and two layers of cotton shirt material. This clothing barrier is an important factor as the materials used can plug a bullet’s cavity and render the hollow point ineffective."
Is this part of the FBI testing? I thought they used four layers of denim. If not, why not stick to the typical testing medium?
Men freely believe that which they desire.

Do these really penetrate better than conventional ball or SWC designs? I imagine the shape has something to do with it but we're still bound by the SAAMI pressure and velocity specs. Using Underwood's website as an example, they have a 125gr +P jacketed flat point listed as good for 1,200 FPS. The Underwood/Lehigh 100gr is listed as having the same velocity. There's also a 140gr Lehigh with a listed speed of 1,000 FPS.
I'd guess all three loads would be pretty close to each other in terms of penetration but would also guess the 140gr would punch the deepest given the additional weight.
Not 38 Special but here's some limited info on one of the Lehigh bullets:
